DNA Replication Process

helicase:opens the helix, by breaking hydrogen bonds ...while Topoisomerase: relaxes the helix.

=O Best video I've seen all day!!! Thank you SO much! It really helped me understand the difference between polymerase I and polymerase III.

HELICASE is not topoisomerase.

Helicase is the enzyme that breaks the hydrogen bonds between the two double helix strands to form 2 single strands for replication... When the DNA is "untwisting" for replication to start, it starts to coil on one end. Topoisomerase cuts the double stranded DNA and rejoins it in the same place to relieve the tension caused by the unwinding... think of it like a shoelace. if you hold both ends while its coiled, you can uncoil it by cutting/rejoining pieces.
